Because America created the atomic bomb, Franklin Roosevelt authorized the atomic bomb to be dropped on Hiroshima.

After Japanese leaders flatly rejected the Potsdam Declaration, President Truman authorized use of the atomic bomb anytime after August 3, 1945. On the clear morning of August 6, the first atomic bomb, nicknamed Little Boy, was dropped on the city of Hiroshima.
